Unsure what the cause of it is, I logged in only to find bold numbers (same as when an ability is on cooldown) that are extremely high. As for when a buff is casted, it will show duration far greater than the original. You will also notice the "next attack" is in 49 days.

Mostly logged in to try my luck getting Mirror Shield, but instead end up doing a bug report. Mostly posting it here in case others have the same issue.
